The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
1ES 2344+514. Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [ 1] 3C 371. 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [ 2] AP Lib.
These black holes could be the seeds of the supermassive black holes found in the centres of most galaxies. [131] It has further been suggested that massive black holes with typical masses of ~10 5 M ☉ could have formed from the direct collapse of gas clouds in the young universe. [127]

Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
As of February 2022, only one isolated black hole has been confirmed, OGLE-2011-BLG-0462, around 5,200 light-years away. [ 2] The nearest known black hole is Gaia BH1, which was discovered in September 2022 by a team led by Kareem El-Badry. Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus.
A supermassive black hole ( SMBH or sometimes SBH) [ a] is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions, of times the mass of the Sun ( M☉ ). Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of ...
Direct collapse black holes (DCBHs) are massive black hole seeds theorized to have formed in the high-redshift Universe and with typical masses at formation of ~ 105 M☉, but spanning between 104 M☉ and 106 M☉. The environmental physical conditions to form a DCBH (as opposed to a cluster of stars) are the following: [ 3][ 4]
